Metabolite Identification
Common Namexi-1-Ethoxy-1-pentyloxyethane
Descriptionxi-1-Ethoxy-1-pentyloxyethane belongs to the class of organic compounds known as acetals. Acetals are compounds having the structure R2C(OR')2 ( R' not Hydrogen) and thus diethers of geminal diols. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H ). Mixed acetals have different R' groups. xi-1-Ethoxy-1-pentyloxyethane has been detected, but not quantified in, fruits. This could make XI-1-ethoxy-1-pentyloxyethane a potential biomarker for the consumption of these foods. xi-1-Ethoxy-1-pentyloxyethane is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review very few articles have been published on xi-1-Ethoxy-1-pentyloxyethane.
